Mounting screw made of V2A (stainless steel) for shift forks. This can be used in Vespa V50, PV, PK S, and PK XL models with damaged shift fork bores. It serves as an alternative to the conical pin, eliminating the tedious task of removing the pin, and making the O-ring replacement less daunting.
While it is indeed a DIY solution, it is effective. Simply drill out the worn hole, tap it with a suitable thread, and screw the bolt in with some threadlocker.
